Migration of JCoFunction in sapjco 3.x - jco

Question

I'm migrating from JCO2.x to 3.x. I have rewritten almost the whole code, but with this I cannot move.
Original 2.x code:
JCO.ParameterList input = new JCO.ParameterList();
input.addInfo("APP_AREA", JCO.TYPE_STRING, 0, 0, 0, JCO.IMPORT_PARAMETER, null);
input.addInfo("XML", JCO.TYPE_STRING, 0, 0, 0, JCO.IMPORT_PARAMETER, null);
JCO.Function function = new JCO.Function(
BAPI_NAMESPACE + "ZZZ",
input, // input
new JCO.ParameterList(), // output
new JCO.ParameterList() // tables
);
My proposed code:
JCoParameterList input = new JCoParameterList();
input.addInfo("APP_AREA", JCO.TYPE_STRING, 0, 0, 0, JCO.IMPORT_PARAMETER, null);
input.addInfo("XML", JCO.TYPE_STRING, 0, 0, 0, JCO.IMPORT_PARAMETER, null);
JCoFunction function = new JCoFunction(
BAPI_NAMESPACE + "ZZZ",
input, // input
new JCoParameterList(), // output
new JCoParameterList() // tables
);
Thing is that JCoFunction cannot be instantiated in this form in 3.x. Should I create function template? Thank you for any hints.

.... a little late response...
You have to get the JcoFunction from your JcoDestination.
e.g.
JCoDestination destination = JCoDestinationManager
.getDestination(destinationName);
JCoRepository repository = destination.getRepository();
JCoFunctionTemplate template = repository.getFunctionTemplate(functionName);
JCoFunction function = template.getFunction();
JCoParameterList input = function_.getImportParameterList();
//set data on input
//execute the function
function.execute(destination);
//access the output
JCoParameterList output = function_.getExportParameterList();
JCoParameterList table = function_.getTableParameterList();
